1. Rear Compartment Lid Release Switch Malfunction 2. Rear Compartment Lid Release Malfunction |
When the rear compartment lid release switch is pressed, the rear compartment lid release signal circuit to the body control module (BCM) is grounded. When the rear compartment lid release signal circuit is grounded, the BCM grounds the coil side of the trunk release relay through the trunk release relay control circuit. With ground applied to the coil side of the trunk release relay, voltage is applied to the rear compartment lid release actuator, opening the rear compartment.
Battery voltage must be between 9-16 volts.
The BCM detects a short to battery in the trunk relay output circuit.
The BCM detects an open or short to ground in the trunk relay output circuit.
The rear compartment lid latch will malfunction.
• | The DTC will be current for as long as the fault is present. |
• | When the fault is no longer present, the DTC will be a history DTC. |
• | A history DTC will clear after 50 ignition cycles |
Luggage Compartment Description and Operation
Control Module References for scan tool information
Command the Trunk Release with a scan tool. The rear compartment lid release actuator should release the trunk lid.
⇒ | If the test lamp is always ON, test the control circuit for a short to ground. If the circuit tests normal, replace the BCM. |
⇒ | If the test lamp is always OFF, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
